Electrical Service Entrance or Exterior Service Drop

Electrical service conductors coming from the utility pole are often smaller than the service wires going into the main electric panel.

This is acceptable due to the fact the wires from the pole are "free to air" which means they can dissipate heat quickly.

Wires inside enclosed spaces such as conduit have little to no ventilation and need to be sized appropriately or excessive heat build up could result.
